This was a terrible experience. I went to the Uffizi Gallery at 10 am, the time indicated on my pass, and to my surprise, the staff at the Gallery told me that I couldn't use the pass since it was the last day of the free museums week, which allowed everyone to enter for free, and that I had to book an appointment like everyone else, through the waiting line. The same thing was informed to me by the staff at the Galleria Dell'Academia.
This required me to completely reschedule my visit, change the plans for my whole itinerary, waste precious time in long waiting queues, and more important, it caused me to lose the opportunity to visit attractions that otherwise I could have attended. It's very likely that a lifetime opportunity was definitely lost.
The TURBOPASS staff didn't let me know about this event in advance. Had they taken the steps to warn me, perhaps I could have rescheduled my visit. But through their lack of action, that caused a situation where I basically bought a completely useless service, they caused me an irreparable damage.
When I demanded a refund, they replied telling me that they e-mailed everyone to let them know about the free museums week. A blatant lie. They never said anything about it. Turbopass offered a partial refund, and when I insisted on the fact that they I never heard from them, again, they said that some of the attractions where free, and therefore, a full refund was not possible.
As I said. This was a horrible experience. Don't bother doing business with these people. There must be other options around.
I may have had the wrong idea about what this pass would do or I just did not use it correctly, but none of the museums recognized this pass for any admission at any time. So, I had to pay the full admission to the Uffizi and the Accademia!
